10. As an alternative to combustion, coal gas can undergo a process called methanation.
3H2 (g) + CO (g) forms CH4 (g) + H2O (g)
Determine the standard enthalpy change for this methanation reaction using the following chemical equations and the value for the standard enthalpy changes.
2H2 (g) + O2 (g) forms 2 H2O (g) H = -483.6 kJ
2C (s) + O2 (g) forms 2CO (g) H = -221.0 kJ
CH4 (g) + 2O2 (g) forms CO2 (g) + 2 H2O (g) H = -802.7 kJ
C (s) + O2 (g) forms CO2 (g) H = -393.5 kJ
